Abstract
The utility model relates to a positive plate of a nickel battery and a battery using the positive plate of the nickel battery. The positive plate of the nickel battery comprises a foamed nickel substrate and positive active substance arranged in the foamed nickel substrate; round corners or bevel edges are formed on the four corners of the foamed nickel substrate; and the battery is a battery using the positive plate. Round corners or bevel edges are formed on the four corners of the foamed nickel substrate, thereby preventing the positive plate from piercing a diaphragm during the rolling process of pole pieces, reducing the occurrence rate of short circuit of the battery, and improving the qualification rate of products.
Description
Technical field
The utility model relates to field of batteries, more particularly, and the battery that relates to a kind of nickel-based battery positive plate and use this positive plate.
Background technology
Existing battery, nickel-based battery particularly, foaming nickel is the right angle as four jiaos of the battery anode slice of base material, referring to Fig. 1, four jiao 11 of pole piece 10 is the right angle, these right angles are relatively sharp, and what have also can have some burrs, in the winding process of pole piece, these right angles and burr might pierce through the barrier film between the positive/negative plate, cause short circuit, make the short circuit ratio of battery and defect rate high, cause the too high and waste of raw materials of production cost.
The utility model content
The technical problems to be solved in the utility model is, causes the high defective of battery short circuit rate, the battery that a kind of nickel-based battery positive plate is provided and uses this positive plate at four jiaos the right angle and the burr of the above-mentioned battery anode slice of prior art.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of nickel-based battery positive plate, it is characterized in that, comprise the Ni-based material of foaming and be arranged on the positive active material of foaming in the Ni-based material, four jiaos of the Ni-based material of described foaming are set to fillet or chamfering.
In nickel-based battery positive plate described in the utility model, described chamfering is 30～60 degree.
In nickel-based battery positive plate described in the utility model, the radius of described fillet is 0.2～4mm.
In nickel-based battery positive plate described in the utility model, described positive active material is the mixture that covers cobalt ball nickel and additive, or Ni (OH)
2Mixture with CoO and additive.
The present invention also provides a kind of battery that comprises above-mentioned nickel-based battery positive plate.
The battery of implementing nickel-based battery positive plate of the present utility model and using this positive plate, has following beneficial effect: owing to be set to fillet or chamfering at the Ni-based material of foaming of the positive plate of battery four jiaos, avoid in pole piece coiling process positive plate to pierce through the phenomenon of barrier film, reduce the short circuit ratio of battery, improved the qualification rate of product.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the schematic diagram of the nickel-based battery positive plate of prior art;
Fig. 2 is the schematic diagram of nickel-based battery positive plate first embodiment of the present utility model;
Fig. 3 is the schematic diagram of nickel-based battery positive plate second embodiment of the present utility model.
Embodiment
As shown in Figure 2, in nickel-based battery positive plate first embodiment of the present utility model, comprise the Ni-based material 10 of foaming and be arranged on the positive active material (not shown) of foaming in the Ni-based material, four jiao 11 of Ni-based material 10 of foaming is set to fillet, described fillet can adopt the mode of punching press to make, and the radius of described fillet is 0.2～4mm.Because four jiaos at the Ni-based material of foaming are set to fillet, have removed four jiaos of burrs that may exist of positive plate, avoid positive plate to pierce through barrier film in the process of reeling and cause short circuit.
In nickel-based battery positive plate first of the present utility model was implemented, described active material was the mixture that covers cobalt ball nickel and additive, or Ni (OH)
2Mixture with CoO and additive.
As shown in Figure 3, in nickel-based battery positive plate second embodiment of the present utility model, four jiao 11 of Ni-based material 10 of foaming is set to chamfering, can adopt the mode of punching out or grinding to make, the angle of chamfering is at 30～60 degree, because four jiaos at the Ni-based material of foaming are set to chamfering, have removed four jiaos of burrs that may exist of positive plate, avoid positive plate to pierce through barrier film in the process of reeling and cause short circuit.
In nickel-based battery positive plate second of the present utility model was implemented, described active material was the mixture that covers cobalt ball nickel and additive, or Ni (OH)
2Mixture with CoO and additive.
First embodiment of battery of the present utility model is to use the battery of the positive plate of the utility model nickel-based battery positive plate first embodiment.
Second embodiment of battery of the present utility model is to use the battery of the positive plate of the utility model nickel-based battery positive plate second embodiment.
In conjunction with the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the novel protection of this use.
Claims (4)
1, a kind of nickel-based battery positive plate is characterized in that, comprises the Ni-based material of foaming and is arranged on positive active material in the Ni-based material of described foaming, and the Ni-based material of described foaming is set to fillet or chamfering for four jiaos.
2, nickel-based battery positive plate according to claim 1 is characterized in that, described chamfering is 30～60 degree.
